As apparent from FIG. 3, the inward prospective frame portion 32 b causes the joining wall portion 31 a to abut against the newly installed upper frame 22 when the joining wall portion 32 a abuts against the finding surface of the newly installed vertical frame 23. In addition, the upper frame member 31 is configured to protrude beyond the found frame portion 31b. The found frame portion 32c is bent and extends from the inward prospective frame portion 32b toward the outer peripheral side. In the first embodiment, the finding frame portion 32c is configured such that the inner finding surface is curved so as to be slightly concave, and the outer finding surface is curved so as to be slightly convex. It is. The finding dimension of the finding frame portion 32 c is set to be larger than the distance from the outer peripheral side surface of the newly installed vertical frame 23 to the joint between the existing vertical frame 12 and the outer wall W. The prospective outward frame portion 32d is bent and extends from the outer peripheral side end portion of the found frame portion 32c toward the outer wall W of the building. A plurality of folding grooves 32f are formed in each of the found frame portion 32c and the expected outward frame portion 32d.

  The vertical frame member 32 is provided with a screw threading wall portion 32g and a screw insertion notch 32h, and a cap member 34 is attached to each upper end portion as shown in FIG. The screw threading wall portion 32g is a fin-like portion that protrudes from the inner surface of the inner expected frame portion 32b facing the outer expected frame portion 32d toward the outer expected frame portion 32d. The finding surface facing the room side of the screw threading wall portion 32g is the joining wall portion 31a of the upper frame member 31 when the joining wall portion 32a of the vertical frame member 32 is brought into contact with the finding surface of the newly installed vertical frame 23. Is formed at a position that coincides with the finding surface of the founding frame portion 31b when it is brought into contact with the finding surface of the new upper frame 22. The screw insertion notch 32h is a U-shaped notch formed from the upper end of each founding frame portion 32c, and is provided in a portion facing the screw screwing wall portion 32g. As shown in FIGS. 7 and 8, the cap member 34 is for closing the upper end opening of the vertical frame member 32, and has a cap body 34a and a wrap portion 34b. The cap main body 34a has a flat plate shape, and is configured in substantially the same shape as the upper end of the vertical frame member 32. The wrap portion 34 b is configured to cover the screw insertion notch 32 h of the vertical frame member 32 when the cap body 34 a is attached to the upper end of the vertical frame member 32.

  Hereinafter, the procedure for attaching the above-described frame members 31 and 32 will be described with reference to FIGS. 4 to 8 as appropriate, and the characteristic part of the first embodiment will be described in detail.

  First, in the first embodiment, as shown in FIG. 4, the vertical frame members 32 are respectively attached to the left and right new vertical frames 23 fixed to the building frame B. Specifically, the joining wall portion 32a of the vertical frame member 32 is brought into contact with the finding surface of the newly installed vertical frame 23, and the mounting screw 40 is screwed onto the newly installed vertical frame 23 from this state via the joining wall portion 32a. Thus, the vertical frame member 32 is held by the newly installed vertical frame 23. The space between the vertical frame member 32 and the outer wall W can be adjusted by appropriately cutting along the folding groove 31e. In this state, as shown in FIG. 3, the vertical frame member 32 covers the existing vertical frame 12, the gap between the new vertical frame 23 and the existing vertical frame 12, and the joint between the existing vertical frame 12 and the outer wall W. This eliminates the risk of exposure to the outside. Although not clearly shown in the figure, it is preferable that the vertical frame member 32 and the outer wall W be sealed with a sealing material.

  As is apparent from FIG. 4, an inrow notch 32 j is formed in advance in the expected inward frame portion 32 b of the vertical frame member 32 so that the end of the upper frame member 31 can be inserted in advance. The inrow notch 32j is formed to match the cross-sectional shape of the upper frame member 31 when the joining wall portion 31a is brought into contact with the finding surface of the new upper frame 22. As described above, the screw-engaging wall portion 32g of the vertical frame member 32 has a finding surface facing the indoor side where the joining wall portion 31a of the upper frame member 31 is in contact with the finding surface of the newly installed upper frame 22. Is formed at a position coinciding with the finding surface of the finding frame portion 31b. Therefore, the inrow notch 32j corresponding to the found frame portion 31b of the upper frame member 31 is formed along the found surface facing the interior side of the screw threading wall portion 32g.

  Next, as shown in FIG. 5, the end portions of the upper frame member 31 are respectively inserted between the vertical frame member 32 and the new upper frame 22 through the inrow notches 32j, and from this state, the joint wall portion 31a is interposed. Then, the upper frame member 31 is held by the new upper frame 22 by screwing the mounting screws 40 into the new upper frame 22. The space between the upper frame member 31 and the outer wall W can be adjusted by appropriately cutting along the folding groove 31e. In this state, as shown in FIG. 2, the upper frame member 31 covers the existing upper frame 11, the gap between the new upper frame 22 and the existing upper frame 11, and the joint between the existing upper frame 11 and the outer wall W. This eliminates the risk of exposure to the outside. As with the vertical frame member 32, the space between the upper frame member 31 and the outer wall W is preferably sealed with a sealing material.

  Next, as shown in FIG. 6, if the connecting screw 41 is screwed into the screw screwing wall portion 32 g via the screw insertion notch 32 h of the vertical frame member 32, the connecting screw 41 and the upper end portion of the vertical frame member 32 are connected. The ends of the upper frame member 31 are connected to each other. Thereafter, as shown in FIG. 7, the cap member 34 is attached to the upper end of the vertical frame member 32, and as shown in FIG. 8, the engagement wall portion 32e of the vertical frame member 32 and the engagement wall of the upper frame member 31 are attached. If the screw covers 33 are respectively attached to the portions 31d, the attachment work of the frame members 31, 32 is completed.

  According to the mounting structure of the frame members 31 and 32 described above, the mounting screw 40 and the connecting screw 41 are screwed together from the side of the surface to be found. Can also be easily installed. In addition, the connecting screw 41 that connects the upper frame member 31 and the vertical frame member 32 is covered and hidden by the wrap portion 34b of the cap member 34, and the frame members 31, 32 are attached to the new frames 22, 23. The screw 40 is covered with the screw cover 33. Therefore, as shown in FIG. 1, when viewed from the outdoor side, no screw is exposed at any location, which is advantageous in terms of appearance quality.

  In addition, the screw threading wall portion 32g for screwing the connecting screw 41 is not provided directly on the found frame portion 32c serving as the design surface of the vertical frame member 32, but from the inner surface of the inward prospective frame portion 32b. It is provided in the protruding fin-shaped part. For this reason, the upper frame member 31 and the vertical frame member 32 are joined without generating a gap between the screw threading wall portion 32g and the found frame portion 31b of the upper frame member 31 regardless of the shape of the found frame portion 32c. Thus, the appearance quality can be further improved.

  Furthermore, the above-described mounting operation can be performed by handling the upper frame member 31 and the vertical frame member 32 individually. Therefore, even if the windbreak chamber is provided at the entrance, the frame members 31 and 32 can be easily carried in without interfering with the opening of the windbreak chamber and without requiring a collaborator. And can be attached.

  In the first embodiment described above, the existing frames 11 and 12 are exemplified in which both the finding dimension and the protruding dimension from the outer wall W are set to be relatively small, but the present invention is not limited to this. . For example, as shown in the modified examples of FIGS. 9 and 10, the existing frames 11 ′ and 12 ′ in which the existing frame members 13 and 14 are attached and the finding dimensions and the projecting dimensions from the outer wall W are set relatively large are modified. In this case, the same can be applied.

  That is, even in the modified mounting structure, the mounting screw 40 and the connecting screw 41 are screwed from the side of the surface to be found, so that it is easy even for buildings that cannot secure a sufficient work space around the corner, such as a corner. Can be attached to. A screw threading wall portion 32g for screwing the connecting screw 41 is not directly provided on the found frame portion 31b of the vertical frame member 32, but is a fin projecting from the inner surface of the inward prospective frame portion 32b toward the outer peripheral side.

Engaging wall portions 132f are provided on the left and right edges of the screw threading wall portion 132a so as to face the second joint wall portion 132c toward the outdoor side, and between the second joint wall portion 132c. A screw cover 134 extending along the longitudinal direction of the vertical picture frame member 132 can be detachably mounted. The first joining wall portion 132b is a portion joined to the finding surface of the newly installed vertical frame 23, and is formed at a portion facing the screw threading wall portion 132a in the prospective direction. When the first joining wall portion 132b faces the room, the screw-engaging wall portion 132a causes the first joining wall portion 131a of the upper frame member 131 to be in contact with the finding surface of the newly installed vertical frame 23. It is formed so as to coincide with the finding surface of the found frame portion 131c when it is brought into contact with the found surface of the new upper frame 22. In the second embodiment, the first joining wall portion 132b is formed by projecting a tongue-like portion in a direction facing each other from a pair of support wall portions 132g projecting from the screw threading wall portion 132a toward the indoor side. Is configured. As is apparent from FIG. 13, the two tongue-like portions constituting the first joint wall portion 132b are provided on the support wall portion 132g so as to secure a gap between them. Further, the outer peripheral side support wall portion 132g slightly protrudes indoors beyond the first joint wall portion 132b, thereby constituting a positioning rib 132h. As shown in FIGS. 12 and 13, the second joining wall portion 132 c is a portion bent at a substantially right angle from the inner peripheral side edge portion of the screw screwing wall portion 132 a toward the outdoor side, and the screw screwing wall portion. It has a width substantially equal to that of 132a and is provided so as to be substantially orthogonal to the first joint wall portion 132b. The finding frame portion 132d is a flat plate-like portion that is bent and extended toward the outer peripheral side from the engaging wall portion 132f. The size of the found frame portion 132d is set to be larger than the distance from the outer peripheral side surface of the newly installed vertical frame 23 to the joint between the existing vertical frame 12 and the outer wall W. The prospective frame portion 132e is bent and extended from the outer peripheral side end portion of the found frame portion 132d toward the outer wall W of the building. Similar to the upper frame member 131, a folding groove 132j is formed in each of the found frame portion 132d and the expected frame portion 132e.

  When attaching the frame members 131 and 132 described above, first, the vertical frame members 132 are respectively attached to the left and right new vertical frames 23 fixed to the building frame B. Specifically, as shown in FIG. 12 and FIG. 14A, the first joint wall 132b of the vertical frame member 132 is brought into contact with the finding surface of the new vertical frame 23, and from this state, the screw threading wall The vertical frame member 132 is held by the new vertical frame 23 by screwing the mounting screw 140 into the new vertical frame 23 via the part 132a and the first joint wall 132b. If there is a gap between the vertical frame member 132 and the outer wall W, it is possible to eliminate the gap by adding the extension plate member 150 to the prospective frame portion 132e. Conversely, when the vertical frame member 132 interferes with the outer wall W, it can be adjusted by appropriately cutting along the folding groove 132j. In this state, the existing vertical frame 12, the gap between the new vertical frame 23 and the existing vertical frame 12, and the joint between the existing vertical frame 12 and the outer wall W are covered with the vertical frame member 132 and exposed to the outside. No fear. Although not clearly shown in the figure, it is preferable that the space between the vertical frame member 132 and the outer wall W be sealed with a sealing material.

  When the vertical frame member 132 is held in the newly installed vertical frame 23, as shown in FIG. 15, an inrow notch 132k is formed in advance so that the end of the upper frame member 131 can be inserted. The inrow notch 132k is formed between the finding surface of the new vertical frame 23 and the finding surface of the upper frame member 131 when the first joint wall 131a of the upper frame member 131 is brought into contact with the finding surface of the new upper frame 22. The vertical frame member 132 may be cut off by the level difference. In the second embodiment, as described above, between the first joint wall portion 132b and the screw threading wall portion 132a, the finding surface of the new vertical frame 23 and the first joint wall portion 131a of the upper frame member 131 are provided. Is secured to a distance corresponding to the level difference between the upper frame member 131 and the upper frame member 131. Therefore, in the present second embodiment, as shown in FIG. 13 and FIG. 14B, only the dimension corresponding to the height of the upper frame member 131 from the upper end of the vertical frame member 132 is used. The support wall portion 132g protruding from the surface is cut off.

  Next, the end portions of the upper frame member 131 are inserted between the vertical frame member 132 and the new upper frame 22 through the inrow notches 132k, respectively. From this state, as shown in FIG. 11, the first joining wall portion 131a is inserted. The upper frame member 131 is held by the newly installed upper frame 22 by screwing the mounting screws 140 into the newly installed upper frame 22 via the. Here, in this Embodiment 2, since the 2nd joining wall part 131b of the upper frame member 131 protrudes rather than the found frame part 131c, when attaching the upper frame member 131, it is to (a) of FIG. As shown, it is necessary to cut away the second joint wall 131b of the portion to be inserted into the vertical frame member 132 in advance. In consideration of molding errors and assembling errors, if the second joint wall 131b is cut to a position beyond the portion to be inserted into the vertical frame member 132, the second joint wall 131b becomes vertical during assembly. There is no possibility of incurring a situation of interfering with the second joining wall portion 132c of the frame member 132.

  In this state, as shown in FIG. 11, the upper frame member 131 covers the existing upper frame 11, the gap between the new upper frame 22 and the existing upper frame 11, and the joint between the existing upper frame 11 and the outer wall W. This eliminates the risk of exposure to the outside. If there is a gap between the upper frame member 131 and the outer wall W, it is possible to eliminate the gap by adding the extension plate 150 to the expected frame portion 131d. Conversely, when the upper frame member 131 interferes with the outer wall W, it can be adjusted by appropriately cutting along the folding groove 131g. The space between the upper frame member 131 and the outer wall W is preferably sealed with a sealing material.

  When the upper frame member 131 is attached to the newly installed upper frame 22 as described above, the screw threading wall portion 132a of the vertical frame member 132 is located in the upper frame member 131 as shown in FIG. The state is in contact with the frame portion 131c. Therefore, when the connecting screw 141 is screwed from the screw screwing wall portion 132a, the upper end portion of the vertical frame member 132 and the end portion of the upper frame member 131 are connected to each other by the connecting screw 141. Then, as shown in FIG. 12, the screw cover 134 is attached to the engaging wall portions 132f and 132c of the vertical frame member 132, and the cover fin portion 133c is attached to the engaging wall portion 131e of the upper frame member 131 as shown in FIG. If the upper frame screw cover 133 is attached in a posture in which the frame member is positioned below, the mounting operation of the frame members 131 and 132 is completed.

  The mounting operation described above can be performed by handling the upper frame member 131 and the vertical frame member 132 individually. Therefore, even if the windshield room is provided at the entrance, the frame members 131 and 132 can be easily carried in without interfering with the opening of the windshield room and without requiring a collaborator. And can be attached. Moreover, since the vertical frame member 132 is connected to the upper frame member 131 by the connecting screw 141, there is no possibility of causing a gap between the vertical frame member 132 and the upper frame member 131. This is advantageous. Further, the connecting screw 141 for connecting the vertical frame member 132 and the upper frame member 131 and the mounting screw 140 for attaching the vertical frame member 132 to the newly installed vertical frame 23 are arranged on the same screw threading wall portion 132a. Thus, if the screw cover 134 is attached to the vertical frame member 132, the mounting screw 140 and the connecting screw 141 can be covered simultaneously.

  Further, since the cover fin portion 133c is provided on the upper frame screw cover 133 attached to the upper frame member 131, the second joining wall portion 131b of the upper frame member 131 is enlarged as shown in FIG. Even when cut out, the cover fin portion 133c is covered, and the appearance quality is not impaired, and the second joint wall portion 131b of the upper frame member 131 and the second joint wall portion 132c of the vertical frame member 132 are not damaged. Interference can be prevented.

  By the way, in the new entrance door in which the frame members 131 and 132 are held on the finding surfaces of the new frames 22 and 23, the expected size of the frame members 131 and 132 from the outer wall W is increased by the amount of the new frames 22 and 23. Can be secured. Therefore, even when the prospective dimensions of the existing frames 11 and 12 and the new frames 22 and 23 are large, the frame members 131 and 132 can cover them. However, as shown in FIG. 12, in the case of a new entrance door with an increased expected size, there is a possibility that the vertical frame member 132 and the screw cover 134 interfere when the new door panel 21 is opened.

  When such a situation is expected, according to the second embodiment, the problem is that the new door panel 21 and the vertical frame member 132 interfere by changing the mounting position of the frame members 131 and 132 with respect to the new frames 22 and 23. Can be prevented in advance. That is, the frame members 131 and 132 of the second embodiment are joined to the prospective surfaces of the new frames 22 and 23 in addition to the first joint walls 131a and 132b that are joined to the finding surfaces of the new frames 22 and 23, respectively. Second joining wall portions 131b and 132c to be provided are provided in advance. As shown in FIGS. 16 and 17, when the frame members 131 and 132 are attached to the prospective surfaces of the new frames 22 and 23 via the second joint walls 131b and 132c, the expected dimensions from the outer wall W are as follows. Although it decreases, the projecting dimension to the outdoor side is greatly reduced. Therefore, as shown in FIG. 17, even when the new door panel 21 is opened largely, there is no possibility that the new door panel 21 may interfere with the vertical frame member 132 or the screw cover 134.

  Here, as shown in FIG. 16, when the upper frame member 131 is attached to the new upper frame 22 via the second joint wall portion 131b, a cover fin portion 133c for covering the second joint wall portion 131b is provided. It becomes difficult to attach the screw cover 133 for the upper frame. However, as described above, the upper frame screw cover 133 applied in the second embodiment can be mounted on the upper frame member 131 in an upside down state. Therefore, if the cover fin portion 133c is positioned upward, the upper frame screw cover 133 can be attached to the upper frame member 131. In this case, a gap is secured between the engagement claw piece 133b disposed below by the engagement fin portion 131h located below the upper frame member 131 and the second joint wall portion 131b. The head and the engaging claw piece 133b do not interfere with each other. Furthermore, according to the upper frame screw cover 133, since the cover base portion 133a protrudes downward from the lower engaging claw piece 133b, the head portion of the mounting screw 140 is covered by the cover base portion 133a. Quality is not impaired.

  In addition, although Embodiment 1 and Embodiment 2 mentioned above have illustrated the entrance door which supported the door panel so that opening and closing is possible, of course, it is applicable also to other fittings. Moreover, although what has connected two frame elements with the heat insulating material is illustrated as a new installation frame, the structure of a new installation frame and an existing frame is not restricted to what is described in embodiment. Further, an inrow notch is formed in the vertical frame member so that the end of the upper frame member is inserted into the vertical frame member, but the upper frame member and the vertical frame member are joined in the opposite manner. It doesn't matter. The construction procedure is not limited to the embodiment, and the vertical frame member may be attached after the upper frame member is attached.
